Hi there,
Working with the QuickBooks Online mobile app allows for tons of flexibility in your bookkeeping. You can work from anywhere and get things done quickly and easily. I know how vital it is to be able to categorize your expense transactions accordingly. I'll explain why you're being prompted to add a tax, and share more information about how to categorize your transactions in the app.
Each expense entered into QBO will need to have a tax code assigned to it. You'll have to choose from the available taxes, make a selection, then continue by saving the transaction. QuickBooks won't allow you to save your expense without a tax code assigned to it. If you were exempt from paying tax on the transaction, you can use Exempt, Out-of-Scope, or Zero Rated as the tax code.
Here's more information about categorizing transactions in the QBO mobile app: Categorize transactions in the QuickBooks Online app.
If you're in need of any additional help, please reach out to our tech support team so an agent can look into this for you.
Have a great weekend.
